Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why CleanRun Air Duct Cleaning Is Covina’s Preferred HVAC Cleaning Company
We built our reputation in Covina on documentation. Every job we run here comes with a camera record of what’s inside the ductwork before we start and after we finish. That matters in this city more than most, because Covina sits at the eastern edge of the LA Basin where prevailing westerly winds push accumulated smog against the San Gabriel Mountains. The result is a dense, gray-brown particulate cake inside ducts that homeowners in West Covina or Glendora just don’t see to the same degree. When we hand Covina customers their photo file, they can see exactly what we removed and what’s left behind. No shop-vac noise, no vague promises.
Tomas Reyes, our owner, set the H.A.V.E.N. Standard in 2013 for one reason: too many Covina homeowners were paying for work they couldn’t verify. Every CleanRun job in Covina follows Haven Standard Clause 1, a written price before any work starts, and Haven Standard Clause 3, background-checked, uniformed techs identified by name before arrival. Our crews have cleaned HVAC systems in homes along East Badillo Street, through the tree-lined blocks north of Badillo, down toward Covina High, and up into the hills near Via Verde.
Our HVAC Cleaning Services in Covina

Evaporator Coil Cleaning
We emphasize evaporator coil cleaning in Covina because this city’s housing stock is largely 1950s through 1970s construction with central air retrofitted into ductwork that predates it. When a coil has years of trapped smog and wildfire ash caked across its fins, the system’s cooling capacity drops even if ducts are spotless. In Covina, a typical evaporator coil cleaning runs $180 to $340 per system. We remove the access panel, photograph the coil face before and after, and use a Nikro coil cleaning solution applied at the manufacturer’s dilution. The photo goes into your job record.

Blower Cleaning
The blower wheel pulls every cubic foot of air your Covina home circulates. When that wheel carries a coating of the valley’s fine particulate, it moves less air per rotation and forces longer run times. Longer run times, especially during Covina’s summer highs that regularly exceed 100°F, mean more particulate pulled into the system. Blower cleaning on a single-unit home in Covina runs $120 to $220. For larger two-story homes with two or three systems, we price each blower separately so you’re never paying a flat whole-house figure that hides per-unit work. We use a Rotobrush whip and negative-pressure extraction to remove what the wheel has collected, then photo the result.

Condenser Cleaning
Covina’s position means outdoor condenser coils collect two things faster than coastal communities: fine dust from fall Santa Ana winds and a film of airborne particulate that settles out of the trapped smog layer. A condenser coil with restricted fins drives up system pressure, shortens compressor life, and makes every August utility bill higher than it should be. Condenser cleaning in Covina runs $90 to $160 per unit. We clean the coil with a professional-grade coil cleaner, straighten any bent fins, and document the before and after with photos.

Air Handler Cleaning
Older Covina homes often have air handlers tucked into closets, attics, or garage corners where they’ve gone years without proper access. When we open an air handler that’s been running in a dusty hall closet for 20 years, we typically find the blower housing lined with dust, the coil partially loaded, and drain pans carrying sludge. Air handler cleaning in Covina runs $200 to $380 per system and includes the blower, coil access, drain pan, and a sanitizing pass if the photo record shows biological growth. This is the service that makes the difference on retrofitted systems where the ductwork was never upgraded to match modern HVAC tonnage.

AfterTrusted Brands We Service in Covina
Our Covina crews work on systems built around Carrier, Lennox, Trane, Rheem, Goodman, and York components, and we maintain our equipment roster with trade-recognized brands like Rotobrush, Nikro, and Honeywell so customers can verify what we’re using before agreeing to a price. What we’ve found in Covina specifically is that older systems with retrofitted AC often have mismatched filter slots, so we carry common replacement sizes including MERV 8 filters that fit the air handler openings found in 1960s and 1970s Covina construction. No trip back to the shop. We come stocked.
Common HVAC Cleaning Problems We See in Covina Homes

- Collapsed flex sections left untouched. In 1950s through 1970s Covina homes, round 6-inch flex duct in attic runs is often crushed or collapsed in multiple spots. A cleaning that skips camera inspection only hits the visible runs and leaves the collapsed sections choking airflow. We camera every run before we start.
- Failed tape seals at register boots. The tape used on original Covina duct systems dries out, cracks, and falls away. When the next Santa Ana wind event pushes fine desert dust through your attic, those gaps become re-contamination points. We seal failed joints during cleaning so the work holds.
- Clogged evaporator coils on retrofitted AC systems. The classic Covina complaint: ducts were cleaned recently but airflow is still weak and cooling is uneven. The coil was never touched. Clean ducts blowing through a loaded coil produce the same symptoms. We clean both, every time.
- The gray-brown particulate signature. Technicians working Covina jobs consistently report a dense, sticky residue inside ducts that looks different from what you’d find 15 miles west toward the coast. It’s the valley’s trapped smog layer mixed with wildfire ash from the San Gabriel range. Camera inspection shows it clearly. Cleaning removes it. Sealing keeps it from returning within weeks.

FAQs - HVAC Cleaning in Covina

A typical Covina three-system home should have every supply and return duct cleaned, not a subset. NADCA’s standard specifies cleaning all supply ducts, all return ducts, the air handler, blower, evaporator coil, and drain pan. The count varies by floor plan: a 1970s two-story in Covina might have 18 to 26 supply registers and 3 to 5 return grilles across three systems. We price per system, and each system’s price includes every duct run connected to it. Call (806) 606-6902 and we’ll walk your specific floor plan with you.
Because flat whole-house pricing hides what’s actually being cleaned. A three-system Covina home is really three separate jobs: separate air handlers, separate coils, separate blowers, separate duct branches. If one system is a 1970s original with collapsed flex and another is a 2010 retrofit, the labor is not the same. Per-system pricing in the $380 to $690 range means you see exactly what you’re paying for on each system. We photograph each one before and after. One flat price would mean someone is paying for work that didn’t happen or not getting work that should have. Call (806) 606-6902 for a written per-system quote.
You should receive a documented photo record showing the inside of every duct run before cleaning and after cleaning, plus a written scope of work listing what was done on each system, and a written warranty. That’s our standard deliverable on every Covina job, every time. No request needed. We also include a written price from before the work started, so your post-job record matches your pre-job quote. If a company in Covina won’t hand you photos of your own ducts, ask why.
Wildfire smoke from the San Gabriel range settles into Covina’s trapped smog layer and gets pulled through HVAC systems during every cooling cycle. After a significant fire season, we see Covina ducts collect a sticky ash-smog residue faster than homes in West Covina or Glendora. For most Covina homes, every 3 to 5 years is reasonable. For homes near the foothills or along the 10 corridor with older, leaky duct systems, every 2 to 3 years makes sense. We’ll camera your ducts and tell you what’s actually there. Call (806) 606-6902 to schedule.
Yes, often dramatically. In 1950s through 1970s Covina homes with AC retrofitted into heating-only ductwork, the coil is frequently the biggest airflow restriction in the entire system. A loaded coil drops static pressure across the whole duct network. Clean the coil, and airflow returns to something closer to what the system could originally deliver. We’ve seen bedrooms go from stale to balanced after a coil cleaning alone. It’s part of every per-system clean we do in Covina.
